Could you explain the differences between the ZV28 subwoofer and the Yorkville LS801P and LS2100P subs?

Here are two graphs. The first one shows the responses of the 3 boxes at low power. These give you an idea of their relative performance at normal listening levels. This graph shows the range of 20 to 200Hz. The second graph shows the responses of the speakers when pushed to their absolute limits. I zoomed in on the 20 to 100Hz range for this graph because all the boxes are not really intended to be used above 100Hz so this focuses on the area you'll be using a subwoofer. Sorry but I didn't remember to match the colors of the lines between the two graphs but you'll be able to recognize the speakers from the similarity of the curves and from the legend at the bottom. You'll see that the horizontal lines are 1dB apart. When you double the number of boxes of the same type, total output is increased by 6dB. So, if you wanted to figure out how many of the LS801P it would take to deliver the same level of sound at 30Hz as a ZV28, you count the lines between the two at 30 Hz and double the number of boxes required for each 6dB. At maximum output, I count 20dB between them. 6dB more would come from 2 boxes, 12dB more would require 4 boxes and 18dB more would require 8 boxes, meaning it would take about 8 of the LS801Ps to reach the same level as one ZV28 at 30Hz. It would take at least 3 of the LS2100P to match the ZV28 at 30Hz. 30Hz is where the quantitative comparison to the ZV28 looks the best and multiples of the other boxes can outperform the ZV28 at higher frequencies but the ZV28 offers very even response throughout the subwoofer range, which the others don't, so the qualitative difference will be noticeable at every level. I hope these graphs and notes help to clarify the differences. Please feel free to ask questions that I may not have answered. Thanks, David Lee
